MATERIAL PROPERTIES OF ALUMINUM 7075 PLATE AND SHEET

Aluminum 7075 sheet, plate, clad sheet and clad plate material properties at room-temperature for T6 / T651 / T73 / T7351 / T76 / T7651 tempers are given in the results chart of following calculator.
These properties are based on material properties charts of aluminum 7075 sheet and plate which are given in MMPDS-01 (Metallic Materials Properties Development and Standardization).

In those instances where the direction in which the material will be used is not known, the lesser of the
applicable longitudinal or transverse properties should be used.

Clad aluminum alloys may have two separate modulus of elasticity values. Primary modulus is the response of both the low-strength cladding and higher-strength core elastic behaviors. This value applies
only up to the proportional limit of the cladding. Above the proportional limits of cladding
materials, a short transition range occurs while the cladding is developing plastic behavior. The material
then exhibits a secondary elastic modulus up to the proportional limit of the core material.

Definitions:

A Basis: The lower value of either the statistically calculated number T99, or the specification
minimum (S-basis). T99 indicates that at least 99 percent of the population
is expected to equal or exceed the statistically calculated mechanical property value with a confidence of
95 percent.

S Basis: S-values are minimum values given in the material specifications and standards. Their
statistical bases are not defined.

Clad: Sheets and plates are clad with high purity aluminum in order to increase the resistance to corrosion of the bare material.

Longitudinal Direction: Direction parallel to the flow in a worked material (grain direction).

Long Transverse: Transverse direction having the largest dimension (width direction).

Short Transverse: Transverse direction having the smallest dimension (thickness direction)

Solution heat treatment: Heating
the alloy to a suitable temperature, waiting at that temperature
long enough to allow constituents to dissolve and rapid cooling to hold the constituents in
solution.

Modulus of elasticity (Young’s
modulus): The rate of change of unit tensile or compressive stress with
respect to unit tensile or compressive strain for the condition of uniaxial
stress within the proportional limit.

Poisson’s ratio: The ratio of lateral unit strain to longitudinal unit strain under the condition
of uniform and uniaxial longitudinal stress within the proportional limit.

Shear stress: A form of a stress acts parallel to the surface (cross section) which has a cutting nature.
